Abstract

The invention provides a rigid-flexible coupling bionic anti-sinking energy-saving buffer walking wheel which comprises a spoke plate, walking wheel leg and foot single bodies and hip joint imitatingparts, and the spoke plate is connected with each walking wheel leg and foot single body through the hip joint imitating parts; a plurality of walking wheel leg and foot single bodies are distributedon the spoke plate in a circular array mode, and each walking wheel leg and foot single body is composed of a walking wheel leg and a walking wheel foot. Wild duck hind limbs are selected as bionic prototypes, and the biological assembly characteristics of rigid-flexible coupling of legs and feet of wild ducks and the constantly changing movement postures of the legs and the feet during movement are simulated. The legs of the walking wheels are bent and restored, so that the effects of energy conservation and buffering are achieved; the toe webs at the feet of the walking wheel are actively opened and closed, so that the ground contact area is changed, and the anti-sinking and anti-sideslip effects are achieved. The rigid-flexible coupling walking wheel leg-foot single bodies actively change the moving posture and the ground contact area, so that the trafficability and traction performance of the walking wheel on soft grounds such as mudflat, muddy and marsh are improved.

Description

technical field [0001] The invention belongs to the technical field of engineering bionics, in particular to a rigid-flexible coupling bionic anti-subsidence energy-saving buffer walking wheel. Background technique [0002] Wheeled mobile mechanisms have the advantages of high efficiency, good ride comfort, and low energy consumption when moving on hard ground. However, problems such as subsidence, slipping, and low traction are prone to occur on soft ground such as deserts, mud, and tidal flats. Compared with the wheel-type mobile mechanism, because the contact points are discrete, the foot-type mobile mechanism has the advantages of high passability and good traction performance on soft ground. In order to integrate the respective advantages of the wheeled mobile mechanism and the footed mobile mechanism, Academician Chen Bingcong imitated the gait of the buffalo and proposed the concept of walking wheels, which solved the problem of tractors under paddy fields. The walki...
